The user wants me to build a complete Mario-style side-scrolling platformer game using Phaser.js, all in a single index.html file. The game should have:

1. A player character that can run and jump
2. Side-scrolling platforms
3. Enemies that can be stomped (like Mario)
4. Collectible coins
5. A goal flag to reach
6. All graphics procedurally generated (no external assets)
7. Using the pre-provided phaser.min.js

Let me first check what's in the current directory to find the exact filename of phaser.min.js.

Good, `phaser.min.js` is already in the current directory. Now let me build the complete game. I'll create a single `index.html` file that:

1. Loads phaser.min.js via `<script src="phaser.min.js">`
2. Contains all CSS inline
3. Contains the full Phaser game code

For the game design:
- Use Phaser 3 with Scene-based architecture
- Procedurally draw everything using Graphics objects (no external images)
- Create a player sprite by drawing on a canvas texture
- Draw platforms, coins, enemies, flag as textures from graphics
- Implement physics (Arcade physics)
- Camera follows player
- Scrolling level with multiple platform sections
- Enemies patrol platforms and can be stomped
- Coins scattered around to collect
- Score tracking
- Goal flag at the end of the level

Let me write this out comprehensively.

Let me verify the file was written correctly and check that phaser.min.js is still there.

The file is created successfully. Let me also verify the key features are present by checking for critical parts of the code - phaser loading, game scenes, and gameplay mechanics.

Everything looks good. Let me provide a summary of what was built.
